Apart from the syntax error, that's one of the worst mis-uses of string
expansions I've seen in a long time. (Admittedly, I have been away from
Exim for 10 days, but still...)

Remember: never use the condition condition without checking for a more
readable alternative first. (I think this is rule 1 of good Exim style.)

In this case you should write:
    ! hosts = 200.91.77.43
